With the acceleration of urbanization, the drawbacks of traditional infrastructure have become increasingly prominent: the "multiple poles" on both sides of the road (traffic signal poles, monitoring poles, street light poles, etc.) have led to spatial fragmentation, which not only affects the beauty of the city, but also causes waste of resources and inefficient management. According to statistics, the number of poles per 100 meters in some urban sections exceeds 20, forming a dual contradiction of "visual pollution" and "spatial redundancy". Against this background, the "one pole for multiple uses" smart street lights came into being. By integrating multiple functions such as LED light pole screens, environmental monitoring, and 5G base stations, it has become a key carrier for solving urban space problems.

With the core design concept of "multiple poles in one", smart street lights upgrade traditional street lights to multifunctional composite poles. LED light pole screens not only replace traditional billboards, but also can publish traffic information, government notices, emergency warnings, etc. in real time, and realize the diversion of human and vehicle information through double-sided display technology. At the same time, the lamp poles are integrated with environmental sensors (PM2.5, temperature and humidity, noise monitoring), video surveillance, charging piles and other equipment, which greatly reduces the number of independent poles, making urban streets cleaner and more functional.

Smart street lights reserve 5G micro base stations, charging piles, and drone dispatch interfaces, and modular design ensures flexible functional expansion. The smart lamp poles in Shuangliu District, Chengdu, use laser radar and AI technology to realize functions such as traffic accident warning and road-blocking vehicle removal, promoting the coordinated development of "car, road and cloud".

From "function superposition" to "value symbiosis", the "tentacle" LED screen of refined governance displays road conditions and parking guidance in real time, and optimizes signal light timing in combination with vehicle networking technology to reduce congestion. By monitoring dust, noise and other data, the pollution source is accurately located to help the "blue sky defense war". Citizens can use the touch screen to query bus routes, scenic spot guides, or scan the code to obtain surrounding commercial information. The lamp poles with integrated charging piles provide emergency power replenishment for new energy vehicles to solve "range anxiety".

Pilot projects in many places have verified the transformation value of smart street lights. Qiucun Town, Fenghua, Ningbo, Zhejiang, reduced the construction of independent poles by 30% through 26 sets of double-sided LED lamp pole screens [citation: user case]. After the renovation of 1,200 smart street lamps in Dingnan County, Jiangxi, the energy consumption decreased by 60% and the brightness increased by 30%. With the help of AI lamp poles, Shuangliu District, Chengdu, achieved a 60% increase in the efficiency of road occupation business evidence collection, and shortened the warning response time of manhole cover displacement to 0.1 seconds.

The ultimate goal of "one pole for multiple uses" is to build a "digital twin" of urban space. With the maturity of 5G, AI and edge computing technologies, smart street lamps will further evolve into real-time collection of urban operation data to support digital twin modeling. Through AR navigation, contactless payment and other applications, deepen smart community services. Combine solar power supply and carbon footprint monitoring to promote the implementation of "dual carbon" goals.

The integration of smart street lamps and LED lamp pole screens is not only a product of technological iteration, but also a milestone in the transformation of urban space from "extensive expansion" to "intensive symbiosis". Through "one pole for multiple uses", cities can unload the "burden" of redundant facilities, give a "new look" to digital governance, and ultimately achieve a triple leap in functionality, aesthetics, and sustainability. With the implementation of more innovative scenarios, this model may become a standard paradigm for global smart city construction.
